To all /w/zom it may concern:

Be it known that I, HARRY C. MC-Conn,

a citizen of the United States residino` in the city of Baltimore and State of Maryland, have invented certain new and useful Improvements in Paste-Applying Machines, of which the following 1s a specifica-tion.

This invention relates to pasting machines especially designed for applying paste to wall paper and other wall coveringsv and materials, an object being to provide a machine whereby paste may be quickly, easily and economically applied to comparatively long strips ofmaterial of any character in a most advantageous manner.

Another object of the invention is the provision of a machine of the above character which includes a paste reservoir and a pasting roller and in which simple and reliable means are provided for regulating' the flow of paste from the reservoir to the roller and for preventing an undue accumulation of paste upon the latter.

Another object of the invention is the pro vision of a machine for regulating the amount of and properly distributing paste o ver the material asthe paste is applied7 and for preventing an overflow/,vof paste from the machine.

Another object of the invention is the provision of novel means for guidingcand tensioning the material during its passage over the pasting roller as `the paste is applied.

Another object of the invention is the provision of means for accommodating roll ors of different lengths, whereby wide and relatively narrow material may be passed through the machine and conveniently handled.

Another object of the invention is the provision of a machine of the above charac'- ter in which the various parts inays be easily separated and the niaohine readily re-asscn'iblcd? so that the said machine may be easily washed to prevent the accumulation of sour paste and thus kept in a clean and sanitary condition. i

lVith the above and other objects in view, the invention further includes the following novel features and details of construction, to beA hereinafter more fully described,- illustrated in the accompanying drawings and pointed out in the appended claims.V

In the drawings z- Figure 1 is a front elevation of a pasting machine constructed in accordance with the invention.

is a fragmentary ielevation Figure l0 is an inner face view of' oney of the end plates of the paper or material roll. ,u Figure llis a similar view looking atthe opposite face of the plate.

Figure 12 is a fragmentary section taken longitudinally through the past-e reservoir. Referring tothedrawings in detail'wherein like characters of reference ydenote corresponding parts, the reference character 15 indicates the :base of the frame ofthe machine from each end of which rises supporting standards 16, the latter being "securedcto the base as indicated at 17.` Y

'Supported vbetween the standards l'isa container 18 whose opposite ends `have extending therefrom spaced parallel horizontally disposed ribs 19 Asofas to provide a horizontal groove 2O at each end of the eon-v These grooves 2O receive rectan' tainer. Y gular lugs 2lv which extend inwardlylfrom the standards 16 and extending through these lugs `are .set screws 22 which engage sockets provided in the ends of the container 18 asY shown in Figure 8 of therdrawings and serve to removably hold the container between the standards.A Y

lhevcontainei.- is divided into a paste rcservoir'23 and acollecting chamber 2l and for this purpose there is provided 'a longitudinally extending partition partition has its opposite ends slidingly mounted within grooves provided by spaced vertically disposed strips-26, so that the partition is removably held in place. The' slightly above the bottoinof theV container as shown at 27 in Figures 6 and l2 of the drawings and for this purpose vertically disposed strips 28 are secured to the partilower edge of the Vpartition 25 isspacedl tion with their lower ends disposed slightly below the Ylower edge 27 of the partition. This provides communication between `the paste reseivoir 23 and the collecting chamber 24 and permits thev paste from the ieservoir to slowly pass into'the chamber. l

Mounted within the collecting chamber 24 is a pasting roller 29 which is'provided withan absorbent cover 30, the said` `cover being` removably'mounted upon studs 31 which have a threaded engagement through the ends of the container 18 and which enter sockets provided inthe ends of the roller. In operation, the roller rotates in the directionk of the arrow shown ink Figures 4 and 6 and the lower outer edge of the coln lecting. chamber is curvedl upwardly as indicatedat 32 so that the action of the roller i will be to force the paste inwardly or in the directionV of. the partition 25 and away from thefopen end of the chamberso asfto prevent overflow oi the paste.

Mounted between the standards 16k isa roll of paper indicated. at 3?), the machine being primarilyV intended to apply paste to paper, Sanitas and 'other wall coverings.'

`This roll 33 includes end platesi, one of which is removably mounted upon a trun-V nionf extending inwardly from one of the standards Y16, while the opposite end plate of the roll 33 has one 'ot its faces provided withY a socket 36 which receives one end ot"A .which surrounds' the tiunnion shank acts to yieldingly force the `trunnion inward. Extending from the inner faces of the end plates 34 are bosses 41 uponwvhich the paper Aor other material is. rolled.-`

This construction is clearly Villustrated in Figure 7 of the drawingsy and the roll is adapted to extend from onestandard to the other. By reference. to this gure it will be seen thatthe machine is designed also for the support of the -shorterroll and Vttor thispurpose there is provided a removable l'iearing standard 42 trom theV bottom of which extend studs or pins 4?, the latter enteringl openings or sockets 44' provided in the base l5. The upper end ol the stanf ard 42 carries a yieldable trunnion 37 which is constructed and mounted a't'ter the manner oit the trininion 3'? previously described.

The strip of paper which is indicated at 45 in Fig-ure 6 of t-lie drawings passes from the roll 33 over an idler roll46, overthe face of the pasting roller 29 and over an idler roll 47, sov that as the paper or material is pulled through the machine paste will be transferred yfrom the roller. 29 to the material as will be readily understood.

For the purpose of providing proper contact' between the material and the 'pasting roller there is provided upper and lower tensioning bars 48 and 49. lThese bars are substantially U-shaped an-d have their opposite'ends pivotally mounted within the standards 16 as shown at 50, so that their' intermediate portions may engage the strip The tensioning bars are yieldingly held in contact with the strip by means: oit springs 51. These springs have oneoif their endsY secure-d to the tensioning bars while their opposite ends are secured in any one of a number of spaced openings 52'pr0'vided inthe standard 16,V whereby adjustment may beetlected for theyregulation of pressure oitl the bars 48 and 49 uponV the strip. The upper wall of the collecting chamber 24 inclines downwardly and forwardlyl as shown at 53 with the lowery edgerotv this wallterminating Vin la vertically disposed portion 54. Slidingly seeuredby means of a nut and bolt to the outer face ot the wall .54 as shown at 55 is a sectional scraper clade 56 which has one ot its sections ot agreater length than the other section so as to cenformto the length of the short roll of paper illustrated bythe dotted lines in Figure 7 ot the drawings. This scraper blade 56 is designed for yielding engagement Ywith the roller 29 sofas-to remove surpluspaste therefrom betorerapplying the paste to the strip' 45, the blade being yieldinglymounted so as to permit the same to move vin a direction away from the `roller when necessary. Thus, by forming the blade lin separate sec'- tionsra's shown in Figure-1 of the drawino's. when the short roll of material vis Vused onlyv one section of the bladey will function. Binding. of' the blade during its movement yas might occur it the blade was madegin a single length will be prevented.

Each section ot the Y'blade has extending.

therefrom spaced'` .rods 57 which pass through openings provided in spaced bracket arms 58 which extend from the topl wall 53`oit' the collecting` chamber. Nuts 59 are threadedly engaged with the outer ends ot the rods. 57' so as to. limit thel downward movement oit' the saidV rods, while springs- 60v which surround the reds act to torce the Y same direction or in a direction opposite the direction of movement of the stript. This will act to spread and prevent lthe, ac'- cumulation of surplus pasteupon the strip the paste being smoothed out and applied to the strip after the manner of application oi paste by the ordinary hand brush. Rotation ot the roller 29 is prevented by means Y or a ratchet wheel 66 which .is fast on the shaft 65 and which is engaged'by a dog 67 pivotally secured to the adjacent standard 16. By preventing rotation of the roller in a direction opposite that indicated by the arrows, paste will be prevented from forcing outward between the bottom of the roller and the bottom of the collecting cham ber. f
